Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particular ly considering the comparative ly sma ll patch
of rubber on each tire that assures that all -important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regular ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overal l condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avo iding d am age
If you have to drive over a curb or similar obstacle, drive very slowly
and as close as possible at a right angle to the curb.
A lways keep chemica ls including grease, oil, gasoline and brake
flu id off the ti res .
I nspect the tires regularly for damage (cuts, cracks or blisters, etc .!.
Remove any foreign bodies embedded in the treads .
Storing tire s
Mark tires when you remove them to indicate the direction of rota ­
tion. This ensures you to be ab le to mount them correctly when you
reinstall them. When removed, the whee
ls or tires should be stored in a coo l, dry
and preferably dark place.
Store tires in a vertical position i f they are not mounted on r ims, in
a horizontal position if they are mounted on rims.
N ew tire s
New tires have to be broken in => &.
The tread depth of new tires may vary, according to the type and
make of tire and the tread pattern.
Hidd en d am ag e
Damage to tires and rims is often not readily visible . If you notice
unusua l vibration or the vehic le pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immediately by an author ized Audi dealer or qualified workshop .
Uni dir ection al tire s
A unidirect ional tire can be identified by arrows on the sidewa ll, that
point in the direction the tire is designed to rotate. You must fo llow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
=> page 298.
Rim s with bolted rim ring *
Light-alloy wheels with a bo lted rim ring consist of several parts .
These parts are screwed together with special bo lts, using a specific
technique. This ensures proper function, seal, safety, and true running of the wheel. For this reason, damaged rims shou ld be
replaced, and you should never repair or dismantle them
=> & .
Rim s with screw -on decorative co vers *
Light-a lloy whee ls can be furnished with interchangeab le decora -
tive covers that are mounted to the rim with se lf -locking bolts. ...

toring system* would not be able to monitor the tire pressure or
warn you if it is necessa ry.
• T he battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
r ecommend us ing facto ry insta lled va lve stem caps. Ask you r autho ­
rized Audi dealer to replace lost va lve stem caps.
T he installation of rep lacement tires with steel cord body p lies in
t he tire sidewall may cause mal functi on of the tir e pressure mo ni­
toring system , and is not recommended (cord material information
in mo lded o n th e ti re sid ewa ll) .
Always check your tire pressure monitoring system * indicator after
r eplacing one or mo re ti res on your veh ic le . I f the ti re p ress ure

& WARNING
• Using incorrect or unmatched tires and I or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always use t ires , rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fa il suddenly,
espe cially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speed s.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tire s may have been damaged
even though the damage cannot be seen that can lead to sudden
tire f ailure and loss of vehicle control.
& W ARNING (continued )
• All four wheels mu st be fitted with radial tires of the same type,
size (rolling circumference ) and the same tread pattern. Driv ing
with different tires redu ces vehicle h andling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for e xample with winter tire s - only u se the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
the ir rated speed can fail suddenly .
• Overloading tires cause heat build-up, sudden tire failure ,
including a blowout and sudden deflation and loss of control .
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chnical reasons it is not always possible to use wheels
from other vehicle s -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked. Redu ced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision.
• Run flat tire s may only be used on vehicle s that were equipped
with them at the fa ctory . The vehicle must have a cha ssis designed
for run flat tires and a factory -installed tire pressure monitoring
s ystem that indicate s a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
autho rized Audi dealer or t ire specialist to see if your vehicle can
be equipped with run flat tires .
If run flat tires are used , they mu st
be installed on all four wheels . Mixing tire types is not permitted. .,

-Screw the threaded end o f the alignment pin from the
tool kit hand -tight into t he now vacant bo lt hole
=>
page 297, fig . 222.
- Then completely unscrew the other wheel bolts as
described above .
- Take off the wheel leaving the alignment p in in the bolt
hole.
Puttin g on th e sp are
- Lift the spare wheel up and carefu lly s lide it over the
alignment pin to gu ide it in place .
- Use t he hexagonal socket in the screwd river handle to
screw in and tighten all w heel bolts
slightly.
- Unscrew the alignment pin and insert and tighten the
remaining w heel bolt slightly like the rest.
- Turn the handle on the jack counter-clockwise to lower
the vehicle until the jack is fully released.
- Use the wheel bo lt wrench to tighten all wheel bo lts
firmly=>
page 295. Tighten crosswise, from one bolt to
the (approx imately) oppos ite one, to keep the wheel
centered.
[ i ] Tip s
Never try and use the hexagona l socket in the handle of the screw­
driver to loosen or tighten the wheel bolts.
• Pull the reversible b lade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bo lts.
• When mounting tires with
uni dire cti on al tread desig n make sure
the tread pattern is pointed the right way~
page 298.
• The whee l bolts should be clean and easy to turn. Check for dirt
and corrosion on the ma ting surfaces of both the wheel and the
hub. Remove all dirt from these surfaces before remounting the
wheel. •
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed the right direction.

i n a sp ec ific dir ection
When using a spare tire with a tread pattern intended for use in a
specific direction, please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direction in the
event of a flat tire, use the spare tire on ly temporarily since the tire
will not be able to achieve its optimum performance characteristics
with regard to aquaplaning, noise and wear.
• We recommend that particular attention be paid to this fact
dur ing wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it instal led on your
vehic le as soon as possible to restore the handling advantages of a
proper ly pointed direction-dependent tire. •
Notes on wheel change
Please read the information~ page 279, "New tires and replacing
tires and whee ls", if you are going to use a spare tire which is
different from the tires on your veh ic le.
